T 0 all whom it may concern.

Be it known that I, EUGEN URBAHN, a citizen of the German Republic,- anda resi dent of Berlin, Germany, have invented cer tain new and usefulImprovements in Means for Supporting Vacuum-Jacketed 'Bottles or OtherReceptacles Within InclosingCasings Therefor, of which the following'isa specification. 1

This invention relates to means for supporting vacuum-jacketed bottlesor other receptacles within inclosing casings there for, andparticularly to a device for resiliently supporting the bottle orreceptacle within the said casing and comprising a number of verticalspring-members or arms laterally engaging the outer wall of the bot tleor receptacle and a resilient horizontally extending member engaging thelowermost or bottom point of the said bottle or receptacle, all of thesaid members being united to form an exchangeable structure ofinterdependent resiliency. I

It is known that vacuum-jacketed bottles are very fragile and for thisreason are usually enclosed in a metallic casing. The provision oftheprotecting casing,however, does not afford suflicient protectionso thatit has been found advisable to further protect the fragile glass body bymeans of resilient supports preferably provided in the bottom part ofthe casing so as to contact with both the casing and the bottle. Theyielding supports hitherto suggested comprise coiled steel wires, flatsteel springs and the, like, but the shape, construction and arrangementof the yielding members heretoforeeniployed are such that a durable orlasting protection is not obtained thereby mainly, since-the yieldingeliicienc) of said members soon decreases and the bottle then will beliable to fracture in case of any shock hitting the bottom of thebottle. v i

The object of this invention is to provide an improved support with aview to remedy this defect andwhichwill form, as hereinbefore stated, ayielding bearing adapted to support the bottom part of the bottle orreceptacle both laterally and from 'below, the construction andarrangement. of the parts being such that when a pressure or force isexerted upon or hits the encased bottle so as to be intercepted andcounteracted'by the resilient support, the laterally jacketed bottlewith the metallic casing engaging orcontacting fingers or arms willtend, owing to the fact that all ofthe' parts form a unit ofinterdependent resiliency, to converge with relation" to each other orto a common central point lying withinthe longitudinal axis of thebottle, sothat even if the resiliency or elasticity thereof diminishesin the course ,of-time, stillga'reliable yielding support will beensured' for any length of time. I i i In the, accompanying drawingforming part of this specification an embodiment of the invention isshown'by way of example, it being understood that changes in the formproportion, size and minor details may be made within the scope of theclaims witl1- out departing from the spirit or sacrificing any of theadvantages of the invention. In

the drawing Figure 1 is anielevation of a broken away at the lower endthereof and Figure 2 is a perspective view showing the resilient supportremoved from the casing.

1 is the vglass bottle of customary shape and. '2, 3 designate thebipartite metallic casing which is likewise of conventionalconstruction. The bottom part 3 of the casing has a flat bottom 1 and isscrewed into the main body 2 of the casing owing to the corrugated shapeof thecy-lindrioal side walls I v of the two parts 2 and 3. v

The resilient support'5 separately shown in Figure 2 may beins'ertedinto the bot-. tom part 3 prior to the attachment of the latter to themain part of the casing, as will be clearly understood from thedrawm strips, three strips 7, 8 and9 of the particular shape shown in Figure-2being employed to constitute thesupport, although in some cases-itmay'be advisable or-desirable to employ more thanythree strips. Thestrips are assembledand connected together' by means of'a single rivet'6 so as to form a unit in the shape ofwhatmay be called a tripod withthe three feet 13 formed by a bend vertically elongated to at the sametime form threeupstanding resilient arms 10, 11 and l2, respectively,adapted tolatera-llv engage or contact with the outer wall of the glassbottle 1.1"

p The distance of 'the free ends of the arms 10, 11 and 12 from eachother or the radial distance thereof from the-longitudinal axis of theglass bottle 1 properly selected to The support 5 is made ofwfiat steelcause the arms, on assemblingthe parts, to yieldingly contact withtheonter wall of the glass bottle without the necessity of overcomingany undue resistance opposed by the latter.

One of the three strips, in the embodiment shown the strip 7, isextended beyond the rivetting point and the elongated end 15 is bent andturned back to form a resilient seat for the lowermost bottom point ofthe bottle. If a pressure is exerted on theturned-over end 15' of thestrip 7 the end 15 will yield in the manner of a spring, but at the sametime the parts of the three strips in the vicinity of the rivet 6 willlikewise yield and move downwards and act as a spring or cushion in casethat the three feet '13 are supported, say by the bottom 1 ofthe part30f the casing. By thus depressing the horizontal parts of the threestrips the free ends ofthe upstanding arms 10, 11 and 12 Will moveradially inwards and exert a gripping action on any body, say the bottle1, inserted thereb'etween, no matter 'whetl'ier they have been in a moreor less slight touch with the latter previous to the depression of thehorizontal parts of the strips, or not.

It will be seen that the bottle 1 duly supported in this manner, asshown in Figure 1, is protected from fracture in a by far better waythan through the usual springs. Any shock or pressure accidentl-yimparted to the top or bottom ofthe vacuumjacketed bottle will beyieldingly intercepted and counteracted by the resilient support 5,whereof the springy seat 15 acts like a buffer spring at the same timetransmitting the received shock partly to the three lateral arms 10, 11and 12 so that the efiect of the shock will be distributed among andabsorbed by the four yielding mem here 15, 10, 11 and 12 and no point ofthe glass bottle will be hit hard enough to undergo fracture through theaction of the acci dental shock,

The three arms keep the bottle alwaysii'i centered position andobviously are adapted to individually absorb lateral shocks. The partscan be readily assembled by siliding the three arms of the support 5onto and over the bottom of the glass bottle 1, insertng .the thuscombined two parts into the main body 2 of the casing and attaching thebottom part3 of the casing to-the main body by screwing the former intothe latter, or dismounted by proceeding in the reverse order. It will beseen that the lowermost portion of the bottom 'part- 3 of the metalliccasing is circumferentially extended to form a circular groove 14. forthe three feet 18 to engage therein either during or prior to theassemblage of the parts shown in Figure 1.

Although it has been found in practice that a (support 5 comprisingthree resilient strips answers well the object aimed at, it may bedeemed convenient in some cases to provide more than three strips whichwould still come within the scope of the invention. For though I havedescribed with great par-- ticularity of detail a specific embodiment ofthe invention, yet, as above intimated, such embodiment is only anexample and it is not to be understood therefrom that the invention islimited. to the particular embodiment disclosed.

l i hat I claim is:

1. A device of the type described tor re siliently supporting avaciunn-jaeketed bottle or receptacle within an inclosing casing,

comprising a number of radially arrang metallic strips firmlyintercom'iected at their meeting point, feet (13) formed in said stripsby bending, upstanding resilient arms (10, 11, 12) projecting from saidfeet, and a means over and above the said meeting point and spacedtherefronii for yieldingly supporting the bottom of the bottle orreceptacle, substantially as described.

2.
